Later I learned it was the people who didn't 'preach' tolerance but actually performed it who were tolerant.

Also I was pretty smart as a child, so while I never believed in Santa I did believe in the good nature of man. Now I know Santa is closer to being real then good nature in men. At least he's advertized, everywhere and has 20k people dressed as him around Christmas minimum.

If I make funny faces, my face will get stuck.
If I touched my nose or ears too much, they'll grow to be huge.
The White Lady and "Little People" (Some scary stories my family would tell me about.)
If I flushed the toilet while I was still sitting on it, a hand would grab me and pull me down.

When I was a child my parents and I would often go to the beach together. For some reason, I always believed waves were made by the breath of a whale that was close by, thus I was always expecting to see a giant whale jumping somewhere. No idea how I came up with that though

When I was 7 I was chewing gum at my aunt's house and he told me not to swallow it because it woukd stay in my stomache for 7 years. That's totally silly now but still I find it funny
I would say things like God, and the Easter Bunny, but I was addicted to Pokemon through my childhood so I didn't really bother with silly things like believing in God.
POKEMON!
